I would start with the soft tbar, the green one with no cut out. Without the center screw, that's pretty soft. The black stock one may be good as traction comes up- at least it was good with foam. I would still run the red mini spring or red spring from the black set. 30 wt/3 hole. Slam the car as much as possible. Drop the camber plate (no spacers, directly on lower arms) so you can get the exact camber gain you want with shimming. Same with upper arms, you can raise or lower the upper arm with spacers on the kingpins.

If you have time, you can also try an upper arm setup like this:
Wow sounds some top secret tips there!!!

Thanks! I will forward it along... and definitely look into all that.

What sort of camber do you run? Toe in?

Do you put anything on the back plate?

What sort of camber do you run? Depends on how you run the angle of the links. I think I wound up with 3mm under the inner ballstud, and 1.5* camber. Also, caster was about 7*
Toe in? 1 deg. out

Do you put anything on the back plate? I would start with 20,000 oil. The heavier you go the more the car will react.

Hi guys,

Just got myself a F104 and loving it!! Running it on asphalt with a silver can motor. Currently running the stock gear ratio of 63T spur and 17T pinion. Would like to try out other ratios, so what kind of pinions should I get (e.g. 0.4, AV or wat)? If I were to use the 93T/104T F103GT spurs, wat kind of pinions then?

Thanks in advance for the help!!

How bout this?

David Jun, Tamiya Hot Shoe Driver etc. told me this weekend at the TCS Nationals that he almost always runs 27 pinion with 93 spur.

I have run 25 thru 29 pinions.

Austiin B., this years Japan trip winner ran 30/93 and called it hot but fast and didn't fade.

Hey Rob, is it legal to install servo facing up for TCS (my current setup for UF1 Series)? I asked one of the tech and all they said is refer to the setup sheet. If it's not there then it's not legal, but I don't see making the servo facing up as illegal since I saw some used angled setup without issue.

Also, I noticed that Austin used servo facing down.

Thanks.

I asked Fred Medel personally and he said it was ok since no parts were altered or used incorrectly..I assume Austin's setup falls under the same ruling.

glad to be able to help.

I use 64 pitch pinions (much easier to get everywhere in all sizes) and Tamiya spurs cuz I like the bearing in the center. Can also use Kimbrough spur gears for an unlimited selection but will need the optional spacer to replace the Tamiya bearing in the center.

Some will scream foul when it comes to mixing gears but I never paid attention to them, works great.

Rcmart carries the parts...also use titanium for the camber links, the aluminum parts bend easily.

Insp Gadget hooked you up..
